FOLDING ANCHOR.

SPECIFICATION forming part of Letters Patent No. 401,654, dated April16, 1889.

Application filed November 28, 1888. Serial No. 292,160. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS S. LAUGHLIN, a citizen of the United States,residing at Port land, in the county of Cumberland and State of Maine,have invented certain new and useful Improvements in Folding Anchors;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to folding anchors in which the stock and the armsfold down against the shank for the purpose of making the articlecompact and easy to stow.

Anchors have before been made in which the arms and stock were folded,but such anchors were not provided with suitable means for holding themeither open or closed, and hence in handling them in either conditionmuch inconvenience was caused.

The object of my invention is to construct such a folding anchor withmeans for securing it either open or closed; and it consists in ananchor having its arms and the two parts of its stock pivoted to theshank with a rule or circular joint, holes through each j ointsection solocated as to coincide with a hole in the shank when the arms orsections of the stock are open, and similar holes located to coincidewhen they are closed, whereby a single pin serves to fasten the saidarms or stock in an open or closed position.

I illustrate my invention in the accompanying drawings, in. which*Figure 1 is a side view of my anchor with the arms open. Fig. 2 is aside view taken at right angles to Fig. 1. Fig. 3 is a detail view ofthe pivoted end of one of the arms.

A is the shank of the anchor having a longitudinal slot or opening neareach end to receive the stock 0 and arms B. The arms B are pivoted atone end of the stock by means of a rule-j oint, each arm being providedwith a circular disk, 13*, having a central pivothole, 2 and twoadditionalholes, b and b, near the perimeter of the disk B A shoulder,B, is also formed on the arm, and has a bearing against the shank whenthe arm is opened out. The holes I) in the two disks B with the shoulderB resting against the shank, they will come in line with each other andwith a hole, I), in the shank, and thus receive a pin, e, which isprovided to pass through the shank and arms to hold the latter inposition. The holes I) in like manner are placed so that they willcoincide with the holes I) and with each other when the arms are closeddown against the side of the shank, as shown in dotted. lines. It willthus be seen that by the use of a single pin, 6, which I preferablysecure to the shank by a chain or otherwise, I am able to fasten thearms in an open or a closed position.

The stock 0 is made in two sections pivoted to the shank by a rule-jointof similar 0011-.

struction to the one described, and is provided with two sets of holes,0 and c, the former of which comes in line with corresponding holes oneach side of the shank when the stock is open and the latter when it isclosed. A single pin, 6, serves to hold the stock either open or closed,as in the case of the arms.

In handling, either open or closed, and in stowing the anchor, it is ofgreat convenience to have the folding parts all secured in place, andthe means which I have here shown for accomplishing this result aresimple and effective, and an anchor thus constructed has the advantageof cheapness, durability, and convenience.

As here shown, the pin c is relieved from strain by the shoulder B; butit is obvious that this shoulder can, if desired, be dispensed with andthe pin made large enough to resist the strain exerted upon it.

I claim- 1.. The herein'described folding anchor having the independentarms and. stock pivoted to the shank by means of a rule joint, holesthrough said joint-sections,located to coincide with. correspondingholes in the shank for the admission of a pin when the parts are opened,and holes located to coincide in like manner when the parts are closed,combined with a pin adapted to enter said holes to retain said parts inan open or closed position, substantially as described.

2. The herein-described folding anchor having the two independent armspivoted to the i In testimony whereof I affix my signature in shank bymeans of a rule-joint, holes through presence of two witnesses. saidjoint, located to register with holes in the shank for the admission ofa pin to retain said THOMAS S. LAUGHLIN. 5 arms when open, andregistering holes in said joint and shank to admit a pin for retainingWitnesses: said arms in a closed position, substantially S. W. BATES, asdescribed. FRANK E.
